AB  - As a result of the worldwide ban on antibiotic growth promoters in food animals, essential oils have
gained considerable importance. Animal meat and carcass quality traits have also been reported to be influenced by
essential oils. This study investigated the effects of common nettle essential oil (Urtica dioica L.) in broiler chicken
nutrition on performance and carcass quality characteristics. For this experiment which has lasted a 42-days, a total of
648 one-day-old broilers hybrid Cobb 500 were used. A total of 12 replicates were used per dietary treatment, leading
to a total of 18 broilers per replicate, of an average initial body weight 34±0.58 g. The three dietary treatments com-
prised a control diet (C), a control diet + 0.5% of nettle essential oil (EO1), and a control diet + 1.0% of nettle essential
oil (EO2). Despite the carcass and breast yields being higher in the essential oil treatments (EO1 and EO2) compared
to the control treatment (C), the thigh yields were unaffected by diet (P>0.05). Shank yield was higher in the EO1
and EO2 treatments as compared with the control (P<0.05) treatment. The weight of the viscera decreased (P<0.05)
in the dietary treatments with the addition of essential oils. The EO2 treatment had a lower meat pH compared to the
other two treatments. Based on the obtained results, it is concluded that the EO2 treatment was equally effective as the
EO1, regarding the carcass traits, and therefore can serve as an alternative to the banned antibiotic growth promoters
in broiler chickens.However further in vivo studies are required to assess the effect of the nettle essential oil on the gut
health, immunity, and welfare of birds.

AB  - The aim of the study was to examine the impact of microbiological
and organic fertilizers on morphological and productive characteristics of triticale
during a three-year period (2009/10–2011/12). A two-factorial field experiment
was arranged using a randomized block design with four replications. The object of
the study was the triticale winter cultivar Odisej, and the following treatments were
applied: a control variant without fertilization, microbiological fertilizer “Slavol”
(Agrounik Serbia) 5.0 l ha -1, organic fertilizer “Biohumus Royal offert” (Altamed
RS) 3.0 t ha -1 + microbiological fertilizer “Slavol” (Agrounik Serbia) 5.0 l ha-1
. The
results showed that the expression of the characteristics was significantly affected
by the environment. The lowest values were obtained in the first year when the
most unfavourable meteorological conditions were observed. The application of
microbiological fertilizer had no impact on the stem length and grain weight per
spike, but it significantly increased the number of fertile spikelets (3.7%), spike
length (7.7%) and grain yield (18.6%). The combined application of fertilizers
provided better results for all the examined characteristics, while in comparison
with the control, the differences ranged from 4.3% for the number of fertile
spikelets to 46.5% for grain yield. The strongest correlation was determined
between the spike length and the number of fertile spikelets (r = 0.939**). The
obtained results lead to the conclusion that under variable environmental conditions, the application of fertilizers has a significant impact on morphological
and productive characteristics of triticale, and consequently on the stability of this
crop production in the organic farming system.

AB  - The cereal grains, which represent the cultivated grasses fruits, supply almost half of the total caloric requirements for humans and provide more nourishment compared with any other class of the food. Out of many cereals used for food, maize, rice, and wheat are the most important food resources for humans, representing 94% of the total cereals consumption. According to the data of the Republic Institute of Statistics for the year 2018, the harvested areas of corn amount to 906,753 hectares. The production of about 7 million tons was achieved with an average yield of 7.7 t/ha according to the Ministry of Agriculture of the Republic of Serbia. Serbia is still among the ten largest exporters of wheat and corn in the world for the period of 2014/15-2017/18. More precisely, it ranks seventh in the export of corn. Utilization of maize products for food animal nutrition (1000 t) is 491,48, and for industrial processing (1000 t) 278,862 expressed as the total consumption (1000 t) is 769,910. Therefore, a total of 103 samples of maize products were analyzed for the presence of toxins, i.e., tropane alkaloids (TAs). The samples were collected from the retail stores in the Republic of Serbia in 2021 and analyzed for the presence of atropine and scopolamine (33 corn grits, 39 polenta, and 31 semolina samples). Therefore, the Recommendation 2015/976/EU on the monitoring of TAs in food was adopted by the EU Commission to obtain more occurrence data on TAs in food. The monitoring extent, however, is restricted because reliable analytical methods and appropriate sensitivity are limited. There was a limit of 1 g/kg for each atropine and scopolamine in cereals containing millet, sorghum, buckwheat, or their derivatives. All the samples were analyzed by the LC-MS/MS. The LOQ was set at 1.0 mu g/kg. Out of the total 103 tested samples, 32 samples (31.1%) were contaminated with atropine and scopolamine in concentrations above the LOQ. The highest concentrations of the studied TAs were observed in a semolina sample-atropine: 58.80 mu g/kg, scopolamine: 10.20 mu g/kg. The obtained results indicate that the TAs concentrations are above the LOQ which can be considered potential human and animal health hazards.

abstract = "The cereal grains, which represent the cultivated grasses fruits, supply almost half of the total caloric requirements for humans and provide more nourishment compared with any other class of the food. Out of many cereals used for food, maize, rice, and wheat are the most important food resources for humans, representing 94% of the total cereals consumption. According to the data of the Republic Institute of Statistics for the year 2018, the harvested areas of corn amount to 906,753 hectares. The production of about 7 million tons was achieved with an average yield of 7.7 t/ha according to the Ministry of Agriculture of the Republic of Serbia. Serbia is still among the ten largest exporters of wheat and corn in the world for the period of 2014/15-2017/18. More precisely, it ranks seventh in the export of corn. Utilization of maize products for food animal nutrition (1000 t) is 491,48, and for industrial processing (1000 t) 278,862 expressed as the total consumption (1000 t) is 769,910. Therefore, a total of 103 samples of maize products were analyzed for the presence of toxins, i.e., tropane alkaloids (TAs). The samples were collected from the retail stores in the Republic of Serbia in 2021 and analyzed for the presence of atropine and scopolamine (33 corn grits, 39 polenta, and 31 semolina samples). Therefore, the Recommendation 2015/976/EU on the monitoring of TAs in food was adopted by the EU Commission to obtain more occurrence data on TAs in food. The monitoring extent, however, is restricted because reliable analytical methods and appropriate sensitivity are limited. There was a limit of 1 g/kg for each atropine and scopolamine in cereals containing millet, sorghum, buckwheat, or their derivatives. All the samples were analyzed by the LC-MS/MS. The LOQ was set at 1.0 mu g/kg. Out of the total 103 tested samples, 32 samples (31.1%) were contaminated with atropine and scopolamine in concentrations above the LOQ. The highest concentrations of the studied TAs were observed in a semolina sample-atropine: 58.80 mu g/kg, scopolamine: 10.20 mu g/kg. The obtained results indicate that the TAs concentrations are above the LOQ which can be considered potential human and animal health hazards.",

AB  - Poultry meat production represents one of the most intensive production in poultry fattening. Broiler's production lasts on average 42 days, which enables quicker income of the employed resources. With the ban of dietary antibiotics usage in poultry meat production, new natural feed additives had to been engaged. This research aimed to investigate the effects of medicinal plants addition to broiler rations on the economic results of the production. Our results have reviled significantly (p  LT 0.05) positive effects. Chickens on medicinal plants (T1) addition have recoded much higher total benefit at the end of production (698.1 €) than chickens on control (T2) treatment (335.6 €). Following the same tendency, the benefit per chicken was also higher in medicinal plant treatment (0.15:0.07 €) and profitability (8.01:3.59%). Upon the gained results, it can be assumed that usage of dietary, medicinal plants expresses a beneficial effect on the monitored economic parameters compared to broilers fed with commercial compound mixtures.

AB  - The goal of the research was to investigate the effect of dietary natural or biotic additives such as garlic, black pepper, and chili pepper powder in poultry nutrition on sustainable and economic efficiency of this type of production. A total of eight dietary treatments with 1200 broiler chickens of hybrid line Hubbard were formed, with four replicates. During the experimental period, chickens were fed with three period mixtures diets of different average costs: Starter compound mixture two weeks (0.38 Euro/kg in all treatments), grower compound mixture next three weeks (0.36, 0.38, 0.40, 0.41, 0.46, 0.39, 0.42, and 0.39 Euro/kg, respectively), and finisher compound mixture for the final week (0.34, 0.36, 0.38, 0.39, 0.44, 0.37, 0.40, and 0.37 Euro/kg, respectively). The experiment lasted a total of 42 days. Upon finishing the experiment, results have shown statistically significant (p   LT 0.05) differences regarding the European broiler index (EBI) as one of the indicators of economic efficacy. The EBI was lowest in the control treatment (220.4) and significantly higher in experimental treatments (298.6), respectively. In cost, a calculation included the cost of feed and used natural or biotic supplements in chicken nutrition. The findings of the study of economic efficiency revealed that the cost per treatment rises depends on the natural additive used. Economic efficiency analysis showed that the most economical natural additive with the lowest cost is garlic (0.68 Euro/kg), while the most uneconomical is treatment with black pepper with the highest cost of body weight gain (0.82 Euro/kg). This higher cost of the gained meat is minimal as a consequence of a much healthier and more nutritious food meant for human use, which often promotes sustainable aspects, compared to conventional and industrialized poultry production.
